Filtration testing for spinnable polymer purity
Ensure the purity of your thermoplastic melts and spinnable polymers by accurately identifying foreign particle concentrations, essential for maintaining optimal production quality and consistency.

Filters and Analyzes Polymer Contaminants
The Filtratest by Brabender is a specialized filtration system designed to ensure the purity of spinnable polymers and thermoplastic melts like PET, nylon, and polypropylene. Utilizing a fine-meshed filter disc, it effectively catches and analyzes foreign particles in polymer melts, crucial for maintaining material integrity. Designed for continuous operation, it employs pressure transducers to monitor particle deposition, facilitating precise quality control. Ideal for chemical producers, polymer manufacturers, and research institutions, it integrates smoothly into laboratory and processing environments. The system supports efficient filtration with quick sieve changes, optimized for detailed analysis and contamination assessment.
